Then you are using a different collation in DB2, or "upper" (which is not standardized,
as far as I know), is defined differently there.

Specify a collation that does what you want explicitly:
SELECT upper('testµ' COLLATE "C");
upper
═══════
TESTµ
(1 row)
But then don't complain if your "ö" and "é" are not uppercased either.
